Abstract

See full text

Certain aspects of the present disclosure generally relate to an adaptive combination power supply circuit. The adaptive combination power supply circuit may be capable of switching between performing as a three-level buck converter and as a divide-by-two charge pump. One example power supply circuit generally includes a first transistor; a second transistor coupled to the first transistor via a first node; a third transistor coupled to the second transistor via a second node; a fourth transistor coupled to the third transistor via a third node; a capacitive element having a first terminal coupled to the first node and a second terminal coupled to the third node; an inductive element having a first terminal coupled to the second node; and a switch having a first terminal coupled to the first terminal of the inductive element, the switch having a second terminal coupled to a second terminal of the inductive element.
